When I wrote sound managing software for the DX7 the checksum always was
ok, but failed for one sound only. For this special sound I patched the
Assembler code, to not calculate the checksum, but to use a fixed
checksum. It wasn't a mistake in the code regarding to e.g. an overflow,
it was Voodoo. However, old devices, not only the DX7, were able to use
transmitted data with bad checksums. At least for old MIDI devices, it's a
seldom, but known issue.
